Hardware Installation
3.1 DIN-rail Installation
The router comes with a DIN-rail kit to allow you to fasten the router to a DIN-rail in any
environment.
DIN-rail Kit Mechanical Drawing (Measurements in mm)
Step 1: Slant the router and screw the DIN-rail kit onto the back of the router, right in the middle of
the back panel.
Step 2: Slide the router onto a DIN-rail from the DIN-rail kit and make sure the router clicks into
the rail firmly.

3.2 Wall Mounting
Besides Din-rail, the router can be fixed to the wall via a wall mount panel, which can be found in
the package.
Wall-Mount Kit Drawing (Measurements in mm)
To mount the router onto the wall, follow the steps:
Step 1: Screw the two pieces of wall-mount kits onto both ends of the rear panel of the router. A
total of eight screws are required, as shown below.
Step 2: Use the router, with wall mount plates attached, as a guide to mark the correct locations of
the four screws.
Step 3: Insert a screw head through the large part of the keyhole-shaped aperture on the plate,
and then slide the router downwards. Tighten the screw for added stability.

3.3 Wiring
WARNING: Be sure to switch off the power and make sure the area is not hazardous before
disconnecting modules or wires. The devices may only be connected to the supply voltage
shown on the type plate.
3.3.1 Grounding
Grounding and wire routing help limit the effects of noise due to electromagnetic interference
(EMI). Run the ground connection from the ground screw to the grounding surface prior to
connecting devices.
3.3.2 Dual Power Inputs
The router has two sets of power inputs, power input 1 and power input 2, on a 4-pin terminal
block on the router’s top panel. Follow the steps below to wire redundant power inputs.
Step 1: insert the negative/positive DC wires into the V-/V+ terminals, respectively. Step 2: to
keep the DC wires from pulling loose, use a small flat-blade screwdriver to tighten the wire-clamp
screws on the front of the terminal block connector.
Note: besides power input, the router can also be powered by a PoE PSE such as switch via its
PoE-enabled LAN port.
ATTENTION
1. Be sure to disconnect the power cord before installing and/or wiring your routers.
2. Calculate the maximum possible current in each power wire and common wire. Observe
all electrical codes dictating the maximum current allowable for each wire size.
3. If the current goes above the maximum ratings, the wiring could overheat, causing serious
damage to your equipment.
4. Use separate paths to route wiring for power and devices. If power wiring and device
wiring paths must cross, make sure the wires are perpendicular at the intersection point.
5. Do not run signal or communications wiring and power wiring through the same wire
conduit. To avoid interference, wires with different signal characteristics should be routed
separately.
6. You can use the type of signal transmitted through a wire to determine which wires should
be kept separate. The rule of thumb is that wiring sharing similar electrical characteristics
can be bundled together
7. You should separate input wiring from output wiring
8. It is advised to label the wiring to all devices in the system

Management Interface
5.1 Installation
Before installing the router, you need to be able to access the router via a computer equipped
with an Ethernet port.
Follow the steps below to install and connect the Router to PCs:
Step 1: Select power source. The router can be powered by +12~48V DC power input, or via a PoE
(Power over Ethernet) PSE Ethernet switch.
Step 2: Connect a computer to the router. Use either a straight-through Ethernet cable or cross-
over cable to connect the ETH1 port of the router to a computer. Once the LED of the LAN
port lights up, which indicates the connection is established, the computer will initiate a
DHCP request to retrieve an IP address from the AP router.
Step 3: Configure the router on a web-based management utility. Open a web browser on your
computer and type http://192.168.10.1 (default router IP of the router) in the address box
to access the webpage. A login window will pop up where you can enter the default login
name admin and password admin. For security reasons, we strongly recommend you to
change the password. Click on System Tools > Login Setting after logging in to change the
password.
After you log in successfully, a Web interface will appear, as shown below. On the left hand side
of the interface is a list of functions where you can configure the settings. The details of the
configurations will be shown on the right screen.
